A millionaire hip-hop mogul has a bold plan to rid New York City streets of firearms: He wants to offer young gunslingers who turn in their weapons mentorships … and Beyoncé concert tickets.

Michael (Blue) Williams, the head of Family Tree Entertainment, has pitched the city’s first private-sector gun buyback program to NYPD brass and is waiting for Police Commissioner Raymond Kelly’s okay.

“We want to get as many guns off the streets, and if this works, we’d like to support it,” Kelly told the Daily News, adding that the proposal needs more study.

If given the green light, Williams — who has managed the successful careers of OutKast, Cee-Lo Green and has the ear of hip-hop and rap royalty — said he’ll solicit help from none other than Beyoncé.

“The Beyoncé show is coming to Brooklyn; the Jay-Z show is coming to Yankee Stadium. Our goal is to reach out to individuals who are in my industry, in my world and who I have an association with and get their support,” Williams, 43, said Monday.

“I think we should all work together to help get guns off the streets,” Williams said.
